A real person answers, day or night
Your walls should never be this quiet and this wet
A stain that grows, a meter that spins at night, a bill that climbs without explanation. We trace every concealed leak to its exact point and price the fix on the spot. Call (02) 9072 0520.
Ground that moves and houses that hide water

How we hunt down your hidden leak
Our core detection services cover every place water hides in a local home, alongside everything else at our plumbing hub.
Under slab and in-wall leaks
Acoustic listening and thermal imaging narrow a concealed leak down to one precise spot, so the opening we make stays only as large as the repair genuinely needs, carefully protecting the plaster, tiles and rendered brick surfaces throughout the home.
Pressure testing the supply line
We isolate sections of pipework and watch for pressure drop, which separates a faulty cistern, a weeping garden tap and a genuine buried leak, pointing the repair at the right pipe first, every time, and saves you money on guesswork.
Meter and usage diagnosis
Every tap closed and the meter still moving tells us within minutes whether a leak is real, roughly how large it has already become, and which side of the main it sits on, before any wall gets opened at all.
Leak locating with camera support
Where a suspected leak involves drainage rather than supply, a CCTV drain inspection reveals cracked joints or root intrusion letting groundwater in, often the real story behind persistent damp patches near the Berowra Valley gullies after heavy summer storms.
Gas line leak checking
Gas was reticulated through these streets during the 1980s and 1990s build-out, so the original joints and meter connections have been ageing quietly for decades, and we thoroughly pressure test every fitting and repair or replace whatever fails the test.
Long runs down the ridge mean leaks travel far
Big blocks, long service runs
A leak that surfaces nowhere near its source
An era buried in the garden
What usually brings locals to call
These are the fault patterns we diagnose most often.
A water bill that jumps
A meter spinning with everything switched off confirms a leak somewhere on the property, and our testing isolates whether it hides under the slab, inside a wall cavity or along the buried service line before we quote.
Damp or stained walls and ceilings
Brick veneer hides moisture well, so a spreading stain usually means water has been travelling inside the cavity for weeks, and thermal imaging traces the path back to the entry point without destructive guessing across plastered walls.
Warm patches on floors
A hot water line leaking under a slab leaves a warm strip across tiles or carpet, and acoustic detection confirms the position precisely, which matters when the alternative is breaking concrete across a family room.
Why acting on a suspected leak matters
Getting it found early pays off three ways.
- Structural protection Reactive clay soils lose strength when a leak dries them unevenly, and footings that shift cost vastly more to rectify than the leak that caused the movement ever would have.
- Smaller repairs A leak found by instrumentation needs a precise, minimal opening, while one left to announce itself through mould and damaged plaster means replacing surfaces along its whole travel path.
- Lower water bills Even a slow concealed leak wastes thousands of litres across a quarter, and on metered accounts that cost lands quietly on every bill until it is found and fixed.
How it works
Our detection process, step by step
- 01
Call and tell us
Ring (02) 9072 0520 and describe what's happening, and a licensed plumber, not an answering machine, will tell you what it likely means, what to stop using, and when we can realistically be there.
- 02
Quote before work
Your plumber inspects the job properly, runs whatever diagnosis it genuinely needs, and hands you a single fixed written price covering the complete fix, with a $0 call out fee and nothing added afterwards.
- 03
Trace and pinpoint the source
We match the method to the suspicion, running acoustic listening along supply lines, thermal imaging across walls and slabs, pressure testing on isolated sections and camera work where drainage is involved, until the fault point is confirmed and clearly marked.
- 04
Backed for life
Everything we complete is covered by our Lifetime Labour Warranty, the promise that outlasts the job itself: if it's not right, we come back. No questions. No cost.
Why choose Your Plumber Cherrybrook
Fixed prices, kept
Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.
Licensed and insured
Your Plumber Cherrybrook works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.
Lifetime Labour Warranty
Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.
Genuinely local response
We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.
When a detected leak turns out to be a burst supply pipe, our burst pipes crew takes over the repair the same day, and recurring water worries fit neatly into a maintenance plumbing schedule.
Where we work
Suburbs our detection vans also cover
Alongside the ridge itself, our detection vans travel weekly through Westleigh, West Pennant Hills, Pennant Hills, Thornleigh and Beecroft, carrying the same acoustic, thermal and pressure testing kit, so a concealed leak across these leafy Hills District streets gets the same treatment.

Leak detection questions Cherrybrook locals ask
How do you find a leak hidden inside a wall or under a slab? Acoustic listening gear, thermal imaging and pressure testing narrow the source down before anything is opened, so only the small section actually affected ever gets accessed, keeping repair costs and mess to a minimum.
What does leak detection cost? The call out fee is $0 and we always inspect first, then hand you a single fixed written price covering both the detection work and the repair before anything begins at all.
How long does finding a hidden water leak usually take? Most detections finish within a single visit, though very slow leaks along long buried runs can take extra testing time to isolate with complete certainty before we quote any repair work.
Will you need to cut into my brick veneer wall? Only where the testing places the fault, and we cut the smallest opening the repair genuinely allows, complete the fix and leave the area clean, dry and ready for patching.
Can a water leak affect my home's foundations or footings? Yes, because reactive clay soil shrinks when a sustained leak dries it unevenly, which can allow footings to move over time, so finding the leak early protects the structure itself.
Do you find leaks in nearby suburbs too? We run detection across Westleigh, West Pennant Hills, Pennant Hills, Thornleigh and Beecroft every week, with the same equipment on board, the same fixed pricing approach and the same licensed plumbers.
